A clamping system having first and second clamping mechanisms with respective contact faces, that are couplable such that the contact faces press together with a coupling force. The first clamping mechanism has first and second elements and at least three clamping spheres, the first and second elements being twistable relative to one another, and the clamping spheres being mounted on fixed positions of the second element to be rollable along a circular line. The second clamping mechanism has groove guides assigned to the clamping spheres which have helical groove courses in clamping portions. When coupling the clamping mechanisms, by twisting the second element relative to the first, first regions of the clamping spheres are moved to a clamping position which presses the contact faces together via coupling force. When coupling, the clamping spheres in the clamping portions roll over large distances, leading to low wear and activation with reduced force.

The present invention provides a tool magazine for a brisk machining center, which includes a T2-axis rotation assembly and an A-axis rotation assembly. The T2-axis rotation assembly can move along the T1 axis. When the axis of the swing head is parallel to the plane including the cutter head or located in the plane including the cutter head, the axis of the swing head is parallel to or overlaps with the linear axis of the cutter head. The present invention further provides a tool changing method for a brisk machining center, which does not require the use of complex devices such as manipulators. The process of tool changing is fully realized by the mutual combination of the Z-axis, Y-axis and T1-axis of the machine tool. Moreover, in the process of tool changing, the operations of gripping and releasing the tool are realized only by combining the movements of a single linear axis, greatly reducing the complexity of the tool changing operation, simplifying the logic of tool changing in the machine tool, making the operation easy, having a simple structure, excellent stability and being easy to maintain.
